EdCTOR-PUM II.

SPECIFICATION forming part of Letters Patent No. 310,896, dated January 20, 1885.

Application tiled June 18s-l. (Model.)

To @ZZ whom it may concern.'

Be itknown that I, HENRY KLEIMAN, a citizen ofthe United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Ejector-Pump, of which the followingisa specification, reference being had to the accompanying drawings.

llhis invention has relation to ejector-pumps for pumping water or other liquids from mines and wells and for extinguishing tiresin buildings where steam is used. and also on board of steamships and steamboats; and it has for its objects to produce asteam-pump or steam water-ejector ofthe class referred to that shall possess superior advantages over others of this class in point of cheapness, simplicity, durability, and general efficiency.

The invention consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure l is a view in elevation of an ejector-pump embodying my im-l provenients. Fig. 2 is avertical longitudinal sectional view, and Fig. 3 is a vertical longitudinal sectional view ot' a modification.

Referring by letter to the accompanying drawings, A designates the suction-pipe, and B the steam-chamber, with two branch pipes, C C, which connect with the discharge-.pipe or delivery-pipe D. These branch pipes are made in two sections, provided with lugs E at their meeting ends, and are suitably packed at the 3 5 joint and connected by bolts F.

Within the steam-chamber B are two steamnozzles, G G', which extend up in the two branch pipes C C and project slightly within the two water-nozzles H H, which are secured within the branch pipes by means orn screwthreads, as shown. These water-nozzles extend up in the branch pipes' (l C, aud terminate a little below the upper end of the web I, th at connects thebranch pipes above the steamchamber B. The web I is bored vertically through its middle, as at J, and through this bore J is passed from above downward a small steam-pipe, K, which connects at its lower end with the steam-chamber B byl a screw-joint, and is provided at its upper end with a small nozzle, L, having an opening, M, about the size of a medium-sized pin-head in a two-inch pump. Steamis admitted to the steam-chamber B through a steam-inlet, N, in one side of said chamber, through steam-pipe O or a steam-hose leading directly from the steamboiler or main steam-pipe. The steam-pipe O or hose should be provided with a stopcock, P, to cut oi't the steam from the steamchamber B when it is not desired to use the pump. 1When the pump is located in a well or coal-mine, the stop-cock should be located at some convenient place-say near the boiler or steam-pipe,or any other convenient place.

`Then the steam enters the steaurchamber B,

it passes through the steam-nozzles G G into water-nozzles H H, and creates a vacuum in the branch pipes C C and draws the water or other liquid up through the water-nozzles, and when the water reaches the steam the latter condenses and leaves its 'force in the water. The small steam-pipe K, with the small nozzle L, now comes into operation, though it did not assist in forming the vacuum, and drives the water on through the dischargepipe to any desired height or distance.

rIhis pump, although a double-acting pump, does not cost more to construct it than to construct others of a less capacity, while it pumps twice the amount that a single-action pump does with the same amount of steam. The working parts are all well iinished, in order to avoid friction.

The pumps now in use lift and force, but they require twice the amount of steam, and` will not force the water to as great a height, owing to the rapid condensation of the steam. In mine the two lower nozzles raise the water, and the third upper intermediate nozzle, L, forces it out through the discharge-pipe.. The water-nozzles H H are plain smooth brass nozzles.

In the modilication I have shown awaternozzle, R, which is composed of two sections, thc lower portion of which is in the shape of the frustum of a hollow cone, and is provided with three notches, S, in its threaded base portion, T. .It is screwed into the branch pipes in place ot the nozzles H H, and the other tapering hollow portion, II, is put in place in the branch pipes C C above the portion R, thereby making a double nozzle.

ICO

The pump starts as soon as the steam is turned on and pumps asteady stream. Then the steam is out oft', the water runs back to the well, so there is no danger. of the pump freezing, and therefore no danger in starting the pump. v Y

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In an ejector steam-pump, the combina tion of the branch pipes C C, separated by a central partition or web, I, but having free communication with each other at the ends where the suction and discharge pipes A D are connected, water nozzles secured within each branch pipe, a steam-chamber, B, formed at the base of the partition or web and opening into each branch pipe below the water-nozzles, and a steam-pipe, K, arranged within the central partition or web, I, and opening into the steam -chamber intermediately between the outer ends thereof', as and for the purpose set forth. Y

h 2. In an ejector steam-pu mp, the combination, with the branch pipes C C, separated by a central web, I, .but having free communication with each other at the ends wherethesuc-l tion and discharge pipes A D are connected, and water-nozzles H, secured with in the branch pipes on each side of the web, of a steam-v chamber, B, formed at the lower end of the web and opening into each branch pipe, an inlet, N, for supplying saidvchamber with steam, nozzles G, secured on the outlet ends of the steam-chamber and opening into the lower ends of the water-nozzles, and a steampipe, K, fitted in a central opening of the Web I, and connected with the steam-chamber intermediately between the nozzles G, as and for the purpose set forth.

3. In an ejectorsteani-pump, the combination, with the branch pipes C C, made in two sections and connected. together, said pipes being separated by a central web, I, but having free communication with each other at the ends where the suction and discharge pipes A D connect', and water-nozzles H H, screwing into the inner faces of the branch pipes and web, of the semicircular-shaped steam-chamber B, formed at the lower end'of the web and extending across and connecting the two branch pipes, steam-inlet N, nozzles G G, attached to the outlet ends of the steam-chamber and extending into the lower ends of the water-nozzles, a central opening, J, provided in the web I, a steampipe, K, fitted in the opening and communicating with the upper i middle portion of the steam-chamber, and a nozzle, L, provided at the upper end of the web I, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signaturein presence of two witnesses.
